I have never seen any one able ride in 12 mph wind at 3rd with any kite. If you are saying when Alameda sensor reads 12(it reads lower than actual wind), then that's a different story. I can have fun at Alamea when it's reading 14 but I was never able ride when 3rd is reading below 16.

Sonny, the sensor at alameda is wierd. When its windy, it is usually blowing close to or above the reading. But it seems when it is light, it reads high. Before the sensor was changed they had some bad bearings in the unit and it did read low all the time. But according to Ikitesurf, they have a new unit as of last year that has been totally calibrated and spot on accurate. But it is only accurate where IT is and not neccessarily for the wind WE get. It is also high up and possibly not affected bythe shadows of the north end of the island. This is all asuming typical directions. when it starts reading from the south and from the north things get a little unpredictable. But there have been quite a few days when it has read 12-15 and i can barely keep a kite up.

Yeah, i knew I would get some crap for that one. But it is not accurate in relationship to what we get where we are. I am sure the sensor itself reads very accurately, but there is some kind of wind sheer or something wierd. But i may not be right about diagnosing what the sensors compensation is. It is very hard to tell. I just know there are days when it says its 15mph and i cant stya out at all. then there are days it says 0-8 and I am overpowered on my 14. And when it says 30-you know its probably blowing 35-40 1000' from shore.

Warmer air "can" be more humid, but obviously the warm air in the Delta in the summer is much drier than the cold air on the Coast at the same time of year. The humidity in the Valley is much lower than it is in the Bay Area/Coast that time of year.

Godsey is always telling us how "cold air sticks to the water" better than hot air. Cold air is always sinking, while hot air is rising (ballon analogy again).
